It’s been quite some time since we last saw Circadian Rhythms rocking a stage with their jazzy, melodic vibrations. But it’s all been for good reason, as they’ve utilized the long hibernation to the fullest by expanding to a seven-piece band and working on new material that will lead to their upcoming EP A Passing Thought. And if the first single, “In the Flowers,” that they recently unveiled is an indication of where their next release is headed, it should be in for a treat tonight at Bourbon & Branch. They’ll be joined by good buddies Laser Background, who have also been working on new material for their upcoming album, CORRECT. This evening will also be a good chance to catch Vermont transplants Hello Shark, whom we’re quite enamored with these days here at The Deli, before they go on a mini-tour with Attic Abasement. Bourbon & Branch, 705 N. 2nd St., 8pm, $10, 21+ – Bill McThrill
